1. As they advanced from this place, the footsteps and dung of horses were observed, and the track was conjectured to be that of about two thousand cavalry. These, as they went before, had burnt all the fodder, and whatever else might have been of use to Cyrus. And here Orontes, a Persian, by birth connected with the king, and reckoned one of the ablest of the Persians in the field, turned traitor to Cyrus; with whom, indeed, he had previously been at strife, but had been reconciled to him. 2.

Afterwards, when Clearchus left the council, he related to his friends how the trial of Orontes was conducted; for there was no injunction of secrecy. He said, that Cyrus thus opened the proceedings:
